OLIFANT Voltage Regulator Rectifier for Polaris Ranger RZR 570/800 — Direct-Fit Replacement, Stable Charging

OLIFANT 4012941 is a direct-fit voltage regulator rectifier designed to replace the charging control unit on a wide range of Polaris Ranger, RZR, PRO XD and Ace models.

If your ATV or UTV shows a weak battery, flickering lights, or inconsistent charging, a faulty regulator/rectifier is often the cause. This OLIFANT unit (part numbers 4012941 / 230-22108) is engineered to restore stable charging for specified Polaris 570 and 800 platforms from the early 2010s through the mid-2020s. It’s supplied as a complete replacement component; verify your vehicle’s model year and connector fit before installing.

Which Polaris models will this regulator rectify?

This OLIFANT regulator/rectifier fits a long list of Polaris models across several years. It covers Ranger, RZR, PRO XD, and Ace series machines commonly used in trail, farm, and utility settings. Confirm compatibility by matching your OEM part number or comparing the old unit to the OLIFANT connector and mounting pattern.

• Ranger 800 (2011–2016), Ranger 570 (2014–2015), Ranger 150 (2018–2024)
• RZR 570 (2013–2016), RZR 800 (2011–2014), RZR PRO XP/Turbo series (2018–2021)
• PRO XD 2000G / 4000G (2020–2021), PRO XD Full-size/Crew (2022–2024)
• Ace 150 EFI (2017–2021); OEM numbers 4012941 and 230-22108

How will replacing the regulator/rectifier affect my vehicle’s electrical system?

Replacing a failing regulator/rectifier stabilizes voltage output from the stator to the battery and electronics. That prevents under‑ or over‑charging, which helps protect lights, ignition components, and battery life. Proper installation restores predictable charging behavior under idle and load conditions.

• Delivers regulated DC voltage to recharge the battery reliably
• Converts AC from the stator into usable DC power for accessories
• Prevents voltage spikes that can damage electrical components

What should I check before ordering and installing this part?

Before purchase, compare the OLIFANT unit to your original regulator/rectifier: check part numbers, connector shape, mounting holes, and wire colors. A visual and electrical inspection of the stator and battery helps ensure the regulator was the root cause. If unsure, capture photos of your existing unit to compare with the product images or consult a technician.

• Match OEM part number (4012941 / 230-22108) and connector type
• Inspect stator condition and battery health to avoid repeat failures
• Confirm mounting dimensions and wiring harness compatibility

How difficult is installation and what tools are typically needed?

Installation is straightforward for someone comfortable with basic vehicle electrical work. You’ll generally need a few hand tools, a torque wrench for specified fastener values, and possibly dielectric grease for connectors. Follow manufacturer torque specs and ensure all connections are secure before testing.

• Common tools: ratchet, sockets, screwdrivers, multimeter for testing
• Disconnect the battery before beginning work to avoid shorts
• Test output voltage after installation at idle and at higher RPM

Who is this for: This OLIFANT 4012941 regulator/rectifier is intended for owners, mechanics, and fleet managers who operate Polaris Ranger, RZR, PRO XD, or Ace units included in the compatibility list and need a reliable replacement charging regulator. It’s suitable for riders restoring charging performance on older machines, service shops stocking common replacement parts, and anyone upgrading a failed or intermittently working regulator. Always verify model and connector fit before purchase to ensure a correct, hassle‑free swap.
